ALONZO C. ARNOLD, OF NORWALK, CONNECTICUT.

WINDOW-BLIND FASTENING.

Specification forming part of Letters Patent No. 50,546, dated October 24, 1865.

.To all whom it may concern:

Be it known that I, ALONZO C. ARNOLD, of thetown of Norwalk, in the county ot' Fairfield and State of Connecticut, have invented a new and useful Improvement in the Mode of Constructing Window -Blind Fastening Protectors; and I do hereby declare that the following is a correct description ofthe same, reference being had to the accompanying drawings, and to the letters ot reference marked thereon.

The nature of my invention consists in the arrangement ot' a pivoted metallic bracket to be fixed on the window-sillto secure the blindcatch.

To enable others skilled in the art to make and use my invention, I will proceed to describe the construction and operation.

In the drawings, Figure lis a sectional view of part of a vsash-frame and sashes with the lower sash raised and a blind partly open, to describe the' hasp and protector. Fig. 2 is the same with the blind closed and the hasp on the pin and the protector on it; Fig. 3, aview ofthe protector when oithe pin 5 Fig. et, a view when the same is on the pin and sash closed.

The folding external blinds of windows have n'snally a pendent hasp to pass over a pin iixed in the window-frame 'sill to hold and secure the blind when closed. This hasp or fastening can be easily lifted up and ot' from the pin from the outside ofthe window by the use of any small instrument inserted under the blind or between the slats, so that an entrance to the window can be easily made by a burglar or others from the outside. t

My present invention and improvement is intended to obviate this andprevent the blinds from being opened from the outside.

The drawings, Figs. 3 and 4, describe the form of my protector, which is simply a plate, A, and attachments to screw onto the windowsill. This plate has two vertical supportingears, B B, and the fastening-pin C. The angular-shaped pivoted bracket D is supported by a pin passing through the ears B B, and has a hole through the lower arm, E, to pass over the pin C, and the other arm, F, will then stand up perpendicular close home to the face of the sash H. To operate this bracket, when the lower sash is raised the bracket-arm F is brought down, which takes the arm E ot't'from the pin C; then pull the blind to and pass the hasp G onto the pin C, which ot' course fastens the blinds. Now turn up the arm F and the arm E passes over the pin C and onto the hasp G, and the arm F then stands perpendicular. Then pull down the sash H and the whole is secured by the arm F being close home to the same, rendering it impossible to liftup the hasp G burglariously without first raising the sash.

This simple article will be found very effective in preventing the opening of blinds from the outside, and is much needed.

What I claim as my invention, and desire to secure by Letters Paten t, is-

The plate and attachments A, the angularshaped bracket D, pin C, catch G, al1 in combination, for the purpose described, when depending on thelowersash being closed to make them effective, substantially as set forth.
